Spinel (pronounced SPIH-nel) is a mineral, a member of the larger spinel group. Chemically, it is a magnesium aluminate (MgAl₂O₄) but can contain other elements, leading to a wide range of colors. Spinels are known for their hardness, brilliance, and durability, often being mistaken for other gemstones, particularly rubies and sapphires. They form in various geological environments, including metamorphic rocks, igneous rocks (like basalt), and alluvial deposits. The gem-quality variety is highly prized in jewelry. Synthetic spinels are also created for use in jewelry and industrial applications, offering a more affordable alternative to natural gemstones while still providing the desired aesthetic and physical properties. Historically, spinel's beauty and relative rarity made it a treasured gemstone by royals for generations.
